Question

The hard yellow tissue that makes up the bulk of the tooth is called the

B) dentin

Accepted Answer

Dentin is the hard,dense,calcified tissue that forms the greatest bulk of the tooth because it forms the largest portion of the crown and root.Softer than enamel,but harder than cementum or bone,the chemical composition of dentin is 70% inorganic and 30% organic matter and water.Unlike enamel,dentin is capable of adding to itself by producing reparative dentin.
